Overview
Hours and minutes without hands
The Jacob & Co. Mystery Tourbillon 44MM, reference SN810.30.AB.UC.A, in an 18-carat white gold case, 44 mm across and 21 mm high. Its 18-carat white gold hour and minute rings are set with pink sapphires and white diamonds, on a white alligator leather strap with an 18-carat white gold folding clasp.
The rings and clasp are set with pink sapphires, and the hour markers are white diamonds.
This watch has no hands. Hours and minutes are shown on two concentric rings set with gems, and a pair of pointers marks the time. Jacob & Co. presents the display as a nod to mystery clocks, whose workings seemed to have no visible explanation.
Hand-wound calibre JCAM49 has 460 components and a 30-hour power reserve. Its tourbillon sits at the centre of the watch, has no upper bridge and turns on three axes, in 60, 120 and 120 seconds. Jacob & Co. says the carriage is covered for the first time by a flower-shaped decorative structure that turns with it. This version is a pièce unique.
